Models 2253TA / 2253S
Model 2253TA is an optional carrier board for model 2253 with breakout connectors for
video, audio, and GPIO signals. Model 2253S is an assembly consisting of a 2253 mounted
on a 2253TA breakout board, in a compact metal enclosure.
GPIO connections
With the 2253 mounted on a model 2253TA breakout board, the 2253's GPIO signals are
available on the 2253TA's 6-pin terminal block. The pinout of the terminal block is listed
in Table 3. Note that the contacts are labeled differently on the 2253TA board and the back
panel of the 2253S enclosure.
